The language of user settings doesn't work for the panels implemented in Angular

[Rikimaru Honjo]

[Issue]

I'm using OpenStack Xena.

I set the language as "Japanese" in "User settings". But the following panels were still the default language.

- Project -> Compute -> Images
- Project -> Compute -> Key Pairs
- Identity -> Roles

[Analysis]

In my analysis, the language of user settings is not applied to the panels implemented in Angular.

The panels implemented in Angular are listed as "ANGULAR_FEATURES" in default.py.

[Additional information]

This issue also occurred in OpenStack Ussuri.

Hi, I have checked Images, keypair, and Roles panel with languages set to Japenese in master and stable/xena branch but am unable to reproduce it. Please see the attachments

Hi Vishal,

OK. I attach images after this. Please wait.

Hi Vishal,

I attached screenshots of my horizon.

And the these are additional inforamtion:

* My openstack environment was deployed with devstack.
* My horizon is commit "d69b1d414760eba09b19e432d67f82e91620d543".
* Other languages in user-settings also cause the same issue. I also put the espanol case in the attached file as an example.

Hi Vishal,

Could you confirm my attachment file?

Hi Rikimaru Honjo, Could you tell me where you run horizon. I mean on Devstack apache port or you run at some other port using runserver command i.e.'tox -e runserver'?

[Rikimaru Honjo (honjo-rikimaru-c6)]

Hi Vishal,

My horizon instance run on Devstack apache port. This is the default deployment of devstack.

$ ls /etc/apache2/sites-available/horizon.conf
/etc/apache2/sites-available/horizon.conf

I attach my local.conf of devstack. Only passwords and host_ip are changed from default values. And I masked passwords.

Rikimaru Honjo, Hi me and tatina from the horizon team tried to reproduce this bug but did not succeed.
Could you check maybe it's your browser cache and refreshing the browser fix it?

I sometimes hit the similar issue that languages in the Angular panels are not changed after changing the language setting.

In my case, hard-reload usually solves the issue. In Chrome, the "normal" reload does not help it. "Hard" reload is required in my case, but "hard" reload is only available when the developer tool is enabled. I think "hard" reload is not an usual procedure.

At the moment I am not sure something can be improved in horizon side, but at least it is worth investigating it.
